2 Claims.

The invention relates to a ventilator and more especially to a windowventilator.

The primary object of the invention is the provision of a ventilatorofthis character wherein the same enables ventilation to aroom'orenclosure without liability of rain sleet, or'the like, entering theroom or enclosure andyat thesaine time, avoiding direct draft upon theoccupants of such rooms or enclosures, the ventilator being also used asa screen for the window openingto exclude insects or the like.

Another object of the invention is the provision of a ventilator of thischaracter wherein a slide is arranged so that the ventilator can beregulated to exclude the passage of air therethrough or to enableincreased or diminished ventilation at the option of a user. I

A further object of the invention is the provision of a ventilator ofthis character'wherein the same involves a construction that enables theeasy fitting thereof within a Window casement and also its removaltherefrom, the said ventilator being of a construction to assure theproper fitting of the same in a window casement within reasonable limitsof sizes thereof.

A still further object of the invention is the provision of a ventilatorof this character which is simple in its construction, thoroughlyreliable and efiicient in operation, strong, durable, readily and easilyadjusted, and inexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction the combination and arrangement of parts aswill be hereinafter fully described in detail, illustrated in theaccompanying drawings, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is an elevation of the ventilator constructed in accordancewith the invention.

Figure 2 is a sectional view taken on the line 22 of Figure 1 looking inthe direction of the arrows.

Figure 3 is a view similar to Figure 1 looking toward the opposite sideof the ventilator and.

partly in section;

Figure 4 is an enlarged sectional view taken on the line 4-4 of Figure 1looking in the direction of the arrows.

Figure 5 is a mutilated perspective view of one of the extensible endmembers of the ventilator.

Figure 6 is a perspective View of the adjustable slide for theventilator.

Similar reference characters indicate correspending partsthroughoutjtheseveral views in i the drawings. i

Referring to the drawings in detail, A-designates' generally theventilator in its entiretyand involves an open frame including end railsiii,

, bottom-rail I land top mill-I 2, respectively; these at their meetingends being united in any suitable manner, while the innermostedg'e' of'the bottom rail i i is formed with an outwardlyinclined or sloping'faceI3 for a purpose presently described.

Fitting the end rails ii) and sli'dably telescoped thereover as well asportions adjacent thereto of i the bottom and top' rails H and i2 are'eixtens i've wings or end pieces it, these being preferably detail-inFigure'tiofthe drawings. 2

. 'These wings or pieces It are adjustably held engaged therewith aframe, that is to-say the end rails is thereof-,1 by screws=i5whichengage in elongated slots it provided in opposite sides of the saidwings or pieces it and fixed in the said frame. Counterseat'edin 'theendrails it] and concealed within the wings or pieces #4 are coiled madefrom sheet-metal of the shape disclosedin compression springs H whichplay against the closed outermost edged portions it of said wings t orpieces M so that these will be maintained under tension. In this mannerthrough the use of the wings or pieces M the frame can be removablyinterfitted within a window casement or the like preferably engaged inthe sash guide- Ways therein.

Arranged with relation to the open center 19 of the frame including therails 18, H and i2,

and opposite sides thereof, preferably counter? seated at 2e, areimperforate panelstl and foraminous screen or screen cloth sections 22respectively. The panels 21 are reversed in their positions with respectto the frame in that at the outer side thereof this panel 2! is at theuppermost half of said frame, while at the inner side of the frame thepanel 2i is at the lower half thereof, which is also true with respectto the relationship of the screen sections 22 in that one 7 sectionthereof at the inner side of the screen is uppermost and the othersection at the outer side of the screen is lowermost of the same. Thesepanels andsections 2i and 22 at their meeting edges are overlapped andunited with each other in any suitable manner as at 23 and 24respectively. Thus, the arrangement of these'panels and'sections efiectsa ventilating space 25 within the open center of the ventilator frame.The panels 2| are preferably made from cel-o-glass, although the samemay be made from any other suitable material-as window pane glass,orrtransparent, or translucent material. The panels 2% and the sections22 are made fixed by suitable fasteners 26 engaged in the frame of theventilator.

The air from without an enclosure enters the ventilator at the outerside thereof through the lower screen section 22, thence flows withinthe space 25 upwardly and delivered from this space through the section22 at the inner side of the ventilator frame and uppermost thereof. Inthis way direct draft upon the occupants of an enclosure or room fromwithout will be avoided, and at the same time, maximum ventilation willbe assured to the room or enclosure. or sloping face [3 of the lowermostrail l I of the ventilator frame functions as a watershed to avoid rain,sleet, or the like, from passing from without to within a room orenclosure through the said ventilator.

Arranged at the inner side of the ventilator frame are verticallydisposed guides 21 for a slide 28 which constitutes a shutter or gatehaving a transparent or translucent center panel 29 preferably made fromcel-o-glass. Now by adjustment of the slide 28 vertically of theventilator frame to partially or completely cover the screen section 22at the inner side of said frame, the ventilation through the ventilatorcan be regulated to an enclosure or. room and thus this slide28functions as a valve for the ventilator.

The slide 28 carries finger grips 30 to enable convenient and easyoperation of the slide for the regulation of the ventilator in the usethereof.

The slide 28 at opposite ends thereof has fitted therewith abutmentflanges 3| coacting with the guides 21 and in this Way endwisedisplacement of the said slide will be avoided and, at the same time,the fitted slide through these flanges 3! will be held in a set positionresultant from frictional contact of the flanges 3| with the guides 21.In other words by the flanges 3| thereon the fitted slide will move truein the guides 21 and be held frictionally in an adjusted position.

The inclined By reason of the arrangement in the structural make-up ofthe ventilator, the room or enclosure cannot be viewed from without thesame through said ventilator, and protection to occupants in this mannerwill be had, yet ventilation is insured to the enclosure or room andalso it will be properly screened.

The ventilator admits light to an enclosure without rendering the samedark and such ventilator can be used with or without the extension wingsor pieces I4 as may be desired.

What is claimed is:

1. A ventilator of the character described comprising an open frame,tensioned extension wings 'at opposite ends thereof, and eachtelescopically fitted thereover, imperforate panels fitted to the frameat opposite sides thereof, one of said panels covering the uppermosthalf of said frame and the other panel covering the lowermost halfthereof, screen cloth fitted to the frame at opposite sides thereof anddisposed in inverse relationship with respect to said panels, animperforate slide fitted to one side of the frame and movable tocovering position with relation to the screen cloth at that side of saidframe, and guides for the said slide and flanges on the slide forfrictionally engaging the guides to hold the slide in an adjustedposition.

2. A ventilator of the character described, comprising an open frame,imperforate panels fitted to the frame at opposite sides thereof, one ofsaid panels covering the uppermost half of said frame and the otherpanel covering the lowermost ,half thereof, screen cloth fitted to theframe at opposite sides thereof and disposed in inverse relationshipwith respect to said panels, an imperforate slide fitted to one side ofthe frame and movable to' covering position with relation to the screencloth at that side of said frame, guides for the said slide, and flangeson the slide for frictionally engaging the guide to hold the slide in anadjusted position.
